     For the first quarter ended June 30, 2004, total sales decreased 8% to
$2,812,800 from the same period in the prior year, and net income decreased to
$52,554 as compared to $281,943 for the same period last year. In January 2004,
the Company completed its acquisition of Innerspace Technology, Inc. ("ITI"), a
company selling its products to the marine industry. ITI is a wholly-owned
subsidiary of the Company, and ITI's balance sheet and results of operations are
consolidated in the Company's financial statements for the quarter ended June
30, 2004.
     For the quarter ended June 30, 2004, total sales of $2,812,800 consisted of
avionics sales of $2,583,071, as compared to $3,057,906 for the prior year, and
sales of marine instrumentation products of $229,729. The decline in sales is
associated with the decrease in commercial sales, which were lower as a result
of a sales promotion in the prior year, and the continuing financial
difficulties in the airline industry. Income before taxes was $87,517 for the
quarter ended June 30, 2004 as compared to $470,212 for the quarter ended June
30, 2003, as a result of the lower sales, change in product mix and costs
associated with ITI.
     The Company has been active in responding to requests for quotation for new
government programs, which could result in new test equipment contracts, and is
now in the process of submitting proposals for several large government
programs. There is no assurance that the Company will be awarded any of these
contracts. The Company continues actively to pursue opportunities in both the
commercial and governmental avionics and marine systems markets, both
domestically and internationally. The Company also continues its efforts with
Semaphore Capital Advisors LLC to pursue growth through acquisitions and
alliances of compatible businesses or technologies
